The mechanical res-onance is fundamentally represented by a series RLC branch, with a resistor modeling the loss [Figure 3(a)]. These components are called the “motional” resistance, inductance, and capaci-tance of the crystal, respectively. With this series branch, the crystal can act as a short circuit at resonance.

WebThe selected crystal must operate in parallel resonance mode to be compatible with TI’s PHYs. A parallel resonant crystal is designed to operate with a specified load capacitance in the oscillator feedback loop. A parallel mode crystal is the same as a series mode crystal, but operates in a different region on its frequency vs. impedance curve. WebThe crystal is operated near series resonance, so it looks like a resistor, and that resistor forms a second lag network for almost another 90 degree phase shift. The inverting amplifier supplies 180 degree phase shift plus a little more because it is not infinite bandwidth. See, for example, Matthys pages 45–53.
